Answer: f(t) = 15 - 1.1t
Step-by-step explanation:
Let t represent the number of hours since the candle was lit.
A 15-inch candle is lit and burns at a constant rate of 1.1 inches per hour. This means that in t hours, the candle that would have burnt is 1.1t
The length of the candle that would be left after t hours is expressed as
15 - 1.1t
suppose f is a function such that f(t) represents the remaining length of the candle (in inches) t hours after it was lit, then
f(t) = 15 - 1.1t

How to solve your question
Your question is
ℎ
=
(
−
4
)
−
ℎ
h=(-4)-h
h=(−4)−h
Solve
1
ℎ − 4
h=-h-4
h=−h−4
2. Subtract from both sides of the equation
3. Simplify
4. Divide both sides of the equation by the same term
5. Simplify
Solution
ℎ = −2
